Driver rolls down her window and angrily says "Settle down. I'm just letting someone get by. I'm not going to hit you." (Ma'am, you choose to block traffic and aim your SUV at me and my child.)

I finish buckling my child, and leave.

AITAH?

I say nothing and make no rude gestures, but my face absolutely says what I am thinking.

I want to make sure that I am safe, and that the encroaching SUV doesn't take off my door or hit my child if he somehow zigs instead of zags and gets out of his car seat.

As I finally convince the child to get in his seat, I see a large black SUV backing towards me.
I turn to make eye contact with the driver (indiscriminate age, F), and hold out my hand to the side and shake my head in a common polite "What do you think you are doing?" gesture.
